Introduction:
C501 series compound polyether is designed for the cyclopentane foaming system. It is mainly used to produce the insulation layer of refrigerators and freezers. It has excellent fluidity, mold release, and excellent thermal insulation performance. When the combined polyether is reacted with polymeric MDI, such as BASF's M20S and Wanhua's PM-200, the foam produced has low thermal conductivity, uniform density distribution, high compressive strength, good adhesion and dimensional stability
